1? F! c E AUTOMATICALLY-OPERATING PAPER-BOX SHAPING AND FINISHING MACHINE.

Application filed May 16,.

My invention relates to an automatically operating paper box shaping and finishing machine.

The object of the invention is to provide a rotatable support having a circular series of mechanisms thereon for forming and clamping the bands of paste board boxes in order toenable the ordinary tops or bottoms as the case may be, to be secured thereto, and then, the extension tops or bottoms; said support having an intermittent rotary movement, thereby permit-ting an attendant to accomplish the first stage of the work on each of a series'of boxes in successive order, while the support is atrest, the second stage of the work commencing wit-h the first box of the series when the support has made a complete rotation; 7

Further, to provide a circular table having an intermittent rotary movement and provided with an endless series of mechanisms for forming the band portions of paste board boxes into any one of a variety of shapes, and clamping said band portions while the bottoms or tops, as the case may be,

and then the extensions are secured thereto by an attendantduring one complete rotation of the table; the extension bottoms or tops being adhesively secured to the original bottoms or tops and clamped thereon, the boxes being removed in successive order upon the next rotation of the table. 7

Further, to provide a rotary series of band forming. and clamping devices, each of which comprises a form of any desired outline and manually operated dies which conform to the shape of the form and which are adapted to clamp a band around saidform and hold said band while the usual bottom ;or top is secured thereto, and while an extension bottom or top is secured to the usual bottom or top, means being providedfor clamping said extension bottom ortop in place, and holding the same until the last box ofthe series is completed, all of the parts being thus held in accurate relation until the adhesive material is set.

These and other objects which will hereinafter appear, are accomplished by the apparatus illustrated in, the accompanying drawings in which:-- i a Figure; l, is a plan view of the improved band. forming and clamping apparatus 1927. Serial no. 191,784; I

Referring to the accompanying drawings: The numeral -1, indicates a supporting structure which is made up ofconnected rectangular side, end and top frames, a platform 2, being supported on the lower members of opposite side frames, as shown in Fig. 2. Upon the platform2, is secured a metal base/ plate 3, having a bearing-socket 4, near its inner. end, vertical brackets or uprights 5 upright 6 intermediateof its ends. To the uprights 5 and'6 isbolted a gear housing,

comprising a horizontal hollow cylindrical part 7, having a flat hollow extension 8, to which is bolted a hollow semi circular' cap 9,

the extension 8 and the cap 9'having regis-' tering bolt flangeslO which are connected by bolts 11 as shown in Fig. 3. AXia'l hubs 12 and '13 are form'ed'in opposite sides of the flat part of the housin one half of'each hub being formed on the extension 8, and the otherhalf on the cap 9.

The cylindrical part 7 of the housing'is formed with a'horizo'ntal projection 14 hav ing depending lugs 15 which are bolted to the'uprights 5 and the 'c'apf9 is formed with a depending lug16 whichis bolted to the upright 6 as clearly shown inFig. fl, a short shaft 17 isin'ounted in the hubs 12 and 13 and on the 'lower'portion of this shaft is v disk '30. The edge portion 37 of the disk keyed or otherwise secured a worm gear 18 whichis enclosed by the extension 8 and its cap 9 and this gear meshes wlth a Worm "pinion 19 in the cylindrical housing 7, which pinion issecured upon a shaft 20 which is has" aon its outer end and a vertical journaled in caps 7 which are bolted to the ends of the cylinder 7.

The shaft 20 extends beyond'one end of the cylinder 7 and its end portion is mounted in abearing 21 which is bolted to the ad- .jacent side of the supporting structure 1. A

stepped belt wheel 22 is secured upon the shaft 20 and this wheel is connected by a e t h-a steppe Pu ley .Ziwvhi i secured upon a shaft 25 which is mounted in bearings securedtto the opposite side of structure 1 from the shaft 20. The shaft 25 belt wheel 26 secured upon'oneend thereof, which is connected by a, belt 27 with a small pulley 28 on the shaft of-an; electric motor 29 which is bolted v,to the platform 2.

Thus, power from the motor 29 is communicatedby' the belt 27 to the wheel '26, the shaft 25 and stepped pulley 2a and thence by belt 23 to wheel22 on theshaft20. and

thence by worm pinion'l and worm gear 18t0'the'shaft'l7. I i

Upon theup'per portion ofthe shaft 17 .is secured a disk or wheel 30 having a hub which rests on'the hub 12 ofthe gear h0usv ing 8 9. The disk 30 has formed thereon or secured thereto a short,'radial arm or lug 31 which extends slightly beyond the circun'iferential edge of the disk, the under side of the lug beingslightly above the upper side of the disk'as clearly shownin Fig. 4. The lug '31has a hole in which is threaded or otl'ie'rwise secured, a boltor pin 32 which, upon each rotation of the disk 30, enters one the'edge portion of a disk 34L which is secured upon a vertical shaft 35, the lower end of which is mountedin the socket bean sixth of a complete rotation before the .pin '82 passes out of th s slotythe next succeedingslot 33 being in position toreceive the pm when it intersects the circular path described by the open end of said slot. The

purpose of tlie'intermittent rotation of the disk 34 will hereinafter appear. The cir-, cumf'erentiial"paths of the disks 30 andS intersect or overlap e'ach'other, aswill be seen by reference to Fig. 3, and as both disks are on-th e same plane, this arrangement is provide'dfforby'inwardly curving the edge por- 33 in arcs36' having-the same radius as the circumference ofthe disk 30, so that the of afseries of radial slots or recesses 33 in 212i) tions'ot' the disksfAbetweenjcachtwo slots edge of the disk 30 will ride successively in the arcs 36', as the disk 34- is rotated by the 34, o'neach side ofthe slots 33, represent 7 as each slot 33 approaches and passes a line drawn through the axial centers of the disks, and therefore, the edgeof the CllSk. is

inwardly curved at 38 on an arc Whose jcen-' ter is on a line which passes through the axlal centers of the disk 30 andpin 32; thus the edge portion of the disk 34, having the greatest diameter rides in the curve38 on each partial rotation of thedisk 34 by the disk 30.

Upon the top of the support 1 is secured a pair of parallel'bars 39 upon which rests a circular metal plate'40 whichis bolted to said bars and is provided with an axial hole through which the-shaft passes. The plate 40 is provided with a circular ball race which is supplied with balls 41 upon which rests a plate 42 also having a ball race. The plate 42 is integrally connected by a hub 48, and ribs 44 with a larger plate 45 which constitutes the base plate for a circular table, to be presently described and the shaft 35 extendsthrough' an axial opening :inthe hub 43 and a suitable distance above the base plate 45 for apurpose which Fig. 1, and the outer ends ofthese channel;

bars-are connected by'a' circular angle bar 48, as shown in Figures 1' and 5, the circu lar bar 48 being about seven feet in diameter.

The-radial bars 47 arefurther eonnected by segmental angle bars 49 which are concentric with the circular bar '48 and a-suit able distance from the same, and upon the horizontal members of thebars 48 and 49 are--sccured segmental table sections 50 in the form-ofwooden blocks which together make up'a ring-like table which supports the box forming and clamping mechanisms which will now be described;

There are preferably six of these mechanisms and as they areidenticalin construction a description of one will s'ur'lice.'-

Upon the table sections 50, and above "the outer end portions'of eaclrof the radial channel bars 47, is ahorizontal metal plate 51 which is supported uponspacing tubes 52, which rest' upon the table sections and the plates are held inv place by bolts'53 which pass through the plate, the spacing tubes and the table sections nuts being screwed upon the bolts and against the undersidesof the table. The plates'are thus supported a suitable distance above thetable to" permit the securing of mechanism to their under sides, as w ll herelnafter appear. Upon the two opposite side edges of each plate 51 are" secured shdeway bars 54 by bolts55, theouter edges of theta-ms benig- \l-shapedu'a' cross section. Upon the V-shaped edges of 1 these, bars are mounted opposite pairs of slides 56 and 57, comprising grooved bars formed With right angled plates 58 on their outer ends, which are braced by integral f webs 59 connecting them With'the slides, as shown in Fig. 8. The-end plates 5801 the;

slides 56 are connected by a wooden bar 60 and this bar and its slides will hereinafter be designated as the frame A. The end plates of the slides 57 are connected by a similar Wooden bar 61, andthis bar and its slides will hereafter be designated as the frame B, and these bars with their slidesare moved toward and away from each other in the following manner :-Upon the under sides'of the slideways 54 are integral, de-

pending lugs 62 and 63, the lugs 62 having pins upon which are rotatably mounted gears 64, while a rod or shaft 65 extends through the lug-s63, and has rigidly mounted thereon gears 66, which mesh with the gears 64.

These gears may be. segmental as in practice,

they make only about a quarter of a complete rotation. 1 I v f The gears 66 are formed with radial ex tensions -67 to which are pivotally attached "the inner'ends of rods 68, the outer ends of which pass through bushings 69, which are loosely mounted in depending brackets 70,- which preferably form an lntegral part of the slide plates57. The bushings 69 areheld in place by nuts 7 1 which are screwed upon the outer ends of-the rods 68.- The gears 64 y are formed on their inner faces with arm-I like enlargements 72' which extend beyondthe peripheries of said gears, and. to the.

outer ends of said'enlargements are pivotally secured the inner ends of rods 73, the

outerends of which passthrough bushings 74 which are loosely mounted in depending brackets 75 formed on theend plates 58 of the slide-s56, the bushings 74 beingzheld in lace b nuts 76 which are screwed LlJOll P y l V the en'dsmfthe rods 73. -One end of the shaft 65' extends beyond the adjacent bear ing lug 63 and is providedwith an opera ting handle 77. By reference to Fig. 5, it will in the direction of the arrow-the gears 66 will draw upon the rods 68, and move the cross bar- 61 and its slide bars 57, inwardbe seen that when the handle 77 is swung and. that simultaneously the gears '64 will 1 draw upon the rods 73, and also move the cross bar-6 0 and its slide bars-56 lnward;

the purpose of movements being hereinafter set forth. e

To the under sideof-fthe crossbar 60 secured a pair of spaced inwardly extending. horizontal abutment brackets 8; and upon the under s1de of the cross bar- 61 are also secured a'pair of similar abutment brackets 79;the brackets on one bar being in direct line with those on the opposite'bar. -Thesebrackets are in the form, sub'atun'txally,oi?-

fiat'narrow castings, the inner ends of which I terminateindepending'right angled aperture-shoulders' 80.

Inthe, aperture shoulders of each pair of izlined abutments7 87 9 is loosely mounted a a tube or rod 81, whichis held against displacement by pins 82 which are passed through thejend portions of the rods back of the shoulders 80, as clearly shown in'Figt 1'. Upon each rod 8lis placed a coil spring 83 which is-held underaslight compression between the shoulders of the opposing abutments, andthese'springs cushion the inward movements of the cross'bars60 and16'1 for a 1rp0se which-will later appear.

ear theouter edge of theplate 51 and on one sided the centerthereof is secured.

a. pair of dependingbrackets 84 inwhich is mounted ,a rod, or shaft 85, the inner end portion-of which'is bent atright angles'to form a leverarm 86, for a purpose which will later appear,;and which is bent in a manner, shown in-Fig. 5. The outer end of rod or shaft 85'extends beyond the adjacent side of the plate 51 and is provided with an operatinghandle 87 ,:the latter handle being on the opposite side of the plate from the handle 77011 therod 65.

Uponthe upper sideiof the plate 51 is secured by screws, ,a block 88, which may be of any desired shape, such as round, square, hexagonal, heart-shaped, etc.,'the block in the present instance, being heartshaped. This block determined the shape.

of the box and therefore is removably secured to theaplateso that other blocks may be employed for any oneof a variety of styles of boxes Cooperating with the block 88 is a pair of formers or dies which taken together a'reof-the same shape oroutline as the'block 88, and'one of these dies 89 is removably secured to theframe A and the other-die 90 is removably securedto the frame B.

To the underside of the die 89, adjacent.

The plunger 96-is'inthe form of awoodenidisk, to-the-under side o'fwhich is secured a thin metal disk 97 having a central threaded aperturesurrounded by aboss 98, whichnormally rests-upon the boss=- of the plate 51, the upper face of theplunger being normally flush with the upper faces of the dies 89 and 90. An eye bolt 99 is'screwed into the metal disk 97; and'extends down through the hole 94k in the plate 51, and the.

end portion of, the lever arm 86 passes through the eye of this bolt,;asshownfin thelever arm 86 raises the plunger '96 "and Figures 5.;andl7; so'that when'the handle 5: 87 of the rod or shaft is swung outward,

thus removesa boxfrom the form -881bya direct verticalpush, by'which binding of the 0 box bandupon the form isnprevented.

()n the-left side of eachjfra'me' A.B and jclose'to the same is a vertical standard 100 in the form of a section of tubing which is secured at its lower end-in hub portion ogfa circular plate 101 which is securedto the A tube or sleeve 102 of less length than the standard 100, is placed over the said standard so as to rest on fthehubof' the-:- plate 10l, and a horizontal bar 103 isfpivotally mounted on the standardin the follow-' ing manner :'Thisbar is preferably 'inthe form of a channel bar upon one end of which is bolted a hinge member 104; having a hole through which the standard passes, the hinge member resting upon the upper end of the sleeve 102. A- cap or nut 105 is screwed upon the upper end of the standard to hold the bar thereon, but 7 permit the freeswinging movement of the bar on the standard.

The opposite end of theibar has a-casting 106 bolted thereon,'the outer end-of-which is yoke-shaped andis adapted to engage thciI upper portion of astandard 107 in the form of a tube which is secured at its lowerend in the hub-portion of'a plate 108 which is secured to the table; this "standard being close to the frameA-B and diametrically opposite the standard 100. A cap 109 is screwed upon the upper'end ofthe standard 107, and is adaptedtoflengage or nearly en-e gage the yoke shaped casting 106, when the bar 103 is in the'position shown in -Figf6, and thus cooperate with the cap-105cm the standard 100 in holding thejbar againstupward movement. A bracket C is bolted -to the bar 103 midway of its length andthis bracket comprises a'body'portion 110 having anuprightbifurcated member 111, in the v upper end ofwhich is mounted a rod which extends beyond'each sideof the casting. Upon the rod 7 isipivotally mounted the cam portion 112 of a vertically disposed lever 113. V i

The cam portion comprises a hub 7 7 which is in the form of twin parallel through which therod 7 passes, a socket member"? to recelve a handle and the earn 7 members which dependfrom the hub 7 and which are curved on' their lower ends to pro- Y v I r andralse the presser block, as Will'beunden vide cam surfaces. flhesecam surfaces are adapted to engage the upper horizontal edges of twin. projections 11% on an abutment 115 having a square opening extending vertically through the-same, through which passes a square presser bar 116 to which the abutment 115 is adj ustably secured by a set screw- 11?. The presser bar is slid-ably mounted in a corresponding guideway 118 in the body 110 of the bracket 0, which is open on the side of the body next the swinging bar 103,'so that the said swinging bar confines the ipresser bar in its guideway as will be understood by reference to Fig, 9.

. The lower end of the presser bar terminates in a, reduced threaded stem 7 which is screwed into a sleeve or bushing 7 which fits in a socketed hub i"?- ona substantially circular platel19, and is held therein by a thumb screw 7*. The plate 119 is and" design as the extension bottoms and tops employed, these tops or bottoms extending about one half an .inch beyond the circumferential edge of 1 the ordinary or regular bottoms and tops. Lugs. or ears 0 are formed at diametrically opposite points on the plate 119 and coil springs d, are connected at one end to the ears 0, and attheir opposite ends to the rod 7 in the upper end of the bracket O. Thethreaded connection of the presser bar 116 with thesleeve in the hub of theplate 119, and the adjustable con nection of the said plate with the presser block120, permits of a vertical adjustment, a turning adjustment, and a back and forth adjustment of the presser-block120 with respect to form 88, or rather, the extension resting thereon, so that the presser block will exactly register withthe said extension,

and will exert the required pressure upon =zthe said extension when, depressed by the cam 7 pulled forward, the cams T'Pride on the pro- H jections 114' of the abutment. 115and the- VVhen the lever or handle 113 is presser block 120 is thereby. forced down upon an extension bottom or top, as the case may be, to clampythe same to the usual bottom or top, and hold it under pressure during a complete rotation of the table,

during which period, the glue or other adhesive becomes set and the bottom or top is prevented from warping.

The die blocks89 and 90 have secured thereon adjustable guides e, which center the extension top or bottonrwith respect to'the 7 block or form 88, when the saidextension is placed thereon, as will later appear. W hen the presser block is depressed, the springs (l,

provided with diametri I Cally-opposite slots a, and a presser block.

are drawn upon or expanded and when the lever 1131s reversed, the springs 6!, contract,

bottom, and then the extension bottom in connection, is as follows, the word extension being used as applicable to either the top or bottomofthe box, as the operation isthe same in either case, I

' The bands F are cut in lengths to exactly conform. to the outline of'the block 88,whatever the shape of the block maybe, and the ends of the band are connected by a narrow stripof tape G,'so that the band is inthe form of a ring. A strip H' is then glued to the band, through .the instrumentality of a.

suitable stripping machine, which is not .,illustrated as it forms no part of the present invention, and this stripis preferably about ne inch wider thanithe band and extends a half inch beyond each edge of the band.

One edge portion of this strip isbent over the edge of the band andv adhered to the .inner face of theband, but the other edge of the strip isleftiunfolded as shown in Figure 13, andtheband isthen ready to be placed on, the fori'ning block 88." Y

Themechanism for rotating the table is set in motion and this mechanism can be governed to movethe table intermittently after such intervals that the periods when the table is at rest will be of sufficient duration to enable the attendant to perform the necessary work in-the production of a box.

. The attendant 'first swings the bar 103 back to the position shown inany one of the mechanisms on the right side of Fig. 1, so that the presser block 120 will be out of the way, andthe handle 77 is pulled. forward to permit the frames A and B to slide apart [under theexpansive action of the springs 83. The regular bottom I is then placed onthe block 88 and the band is placed around this said block with the'unfolded edge of the strip H uppermost and is pressed down until it :re sts upon the plate- 51, the band being about onesixteenth of an inch wider than the thickness of the block 88 so as to surround the bottom I, as shown in Figures 14: and 15. I handle 77 inward whereby the inter-meshing The attendantthen swings the gears 64 and 66' are causedtodraw-upon the rods 73and 68, which in turndraw upon theframes'A and B, and the dies or formers 89' and 90 are thereby moved inward against the band and clamp thesame againstthe block'88 with a resilient pressure. I The unfolded portion of the strip H is then folded down upon the bottom I, thereby securing the bottom to the'band. 1 Glue is then applied to the bottom .1 around the edge ortion thereof' or to the extension J as may e found most practicable and the extension J is placed upon the bottom I, the guides re, centering it so that it will: beconcentric with the band F,'but will extend a half inch beyond the same at all points. The bar 103 is then swung to the position shown in Fig; 6, when the presser block will'be directly above the extension J and a slight distancefrom it, the lever 1'13-is drawn upon and the presser block is forced'down upon the extension J in the manner-before described, and the said' extension is thus clamped'against the boxvbottorn and so held until the table makes a complete rotation during which time the glue hasbecome set, and this part of the box is completedi The operationis' repeated until six half boxes have" been completed, when'the table will have made acomplete rotation, and the first halfj box of the series isready to be removed. The attendant thenpushes the lever 113 which releases the cams 7 and' the presser block 120 is raised. from the extension bythe Springs (2. "The bar 103' is swung around so thatthe presser block willentirely uncover the extension'J' and the lever 77 is swung outward which permits the framesA and B" together with thedies'89 and 90 to 'slide apart under the action of the springs 83. The lever 87 is then drawn upon'to raise theplunger 96' in, the manner previously described, and the plunger is thus in their open movements by the pi1is82; in the rods or tubes 81, which extend through the said springs, the pins 82' engaging the brackets 78, as will be understood-byqreference'to 'Fig. 7; To the ivot pin 121 which connects oneofthe rods 93 of'each frame A with, the gear fi l, is secured one end of. a cable-122 which passes down through an opening-in the table and over and around a sheave wheel 123, which is mounted in a bracket 124 which is secured to the under side of the table, as shown in Fig. 5.

The other end of this cable, connects with one end of a coil spring 125, the op- "posite end of which is secured to one end of a rod 126, the opposite end of which is secured to one of the radial channel bars 47, (seeFig. 1). When the lever 77 is operated in spreading the framesA and B apart the "cable 1'22;draws upon thespring 125, thus 1 2 7 and 128;

preventing a quick or sudden opening-move ment ofthe frames, When'the lever 77 is operated to close the frames, the rods 7 3 are instantly acted upon and the frame :A- is first movedinward towardsthe block, 88, but the rods-68 arenot actuated until the gear 66;i'-otates sufliciently to shift the pull on the said rods 68 from belowto above the center of the shaft 65, after-which they will draw upon and move the frames B inward. When the frames are closed againstthe'block 88, or ratheragainst theband surrounding,

the block, the line of pull on the rods 73 is shifted from above, to below the center oft-he gears 64 as shown in Fig. 5 thereby locking the frames in closed position.

The spring 125 contracts as the frames close, and this spring, drawing under the pivot 121.: which connects the inner end of the rod? 3 tothe gear 64, prevents the frames A and B fromspringingapart.

In Figures 11 and 12 is illustrated the means-used in connection withthe dies and form block in making half depth boxes- 01 boxes for; accommodating a single layer- 01" goods, In carrying out this feature, I employa pain of spacingblocks-127and 128 which are half the thickness ofthedies 88 and 89,- the block 127 fitting; in the. box form recess, in the die-89 and the block 128 fitting in the corresponding recess in the die 90,

these blocks resting-upon the plate 51. The blocks 127' and' 128- are held apartby coil springs 129, which surround: rods 130,'supported in alined-holes in the opposing ends 7 of the said blocks, the ends of the springs entering-recessesin the ends'of the blocks as shown The form block 88 used in this connection, is slightly less thanhalf the thickness of the dies, but flushwith thetop surface of: the dies,and this form block is supported on av block 131 which is slightly -more than one half' the thickness of the dies thusdefining a slight clearance'space 132 be tween the form block, and thespacing blocks The supporting block 131 is smaller than the form block 88 and the spacing blocks'127 and 128 are recessed to fit around the said supporting bloclnas clearly shown in. Fig.11. The formerblock and its supportingbl'ock are secured to the plate 51-by the same bolts 132. In this connection I maydispense with the wooden plunger block and use only a thin metal plunger plate or disk 133. VVhen the attachement for makingsingle layer boxes is used, the box band will. restupon the spacing blocks 127 and 128, as will; be. understood by reference to Figures 11 and. 12, the box forming operation being the same. as described in con nection with full depth boxes.

Theshaft 35 toiwhichi the table is, secured, extends a suitable distance above the table, and a much smaller table 134; is secured thereon by means of a circular plate 135 which is secured to this table and is provided with a hub which registers with a hole in the table, the shaft 35 passing through the hub and the hole in the table, and the hub being secured to the shaft 35 by a set screw 136.

Bottoms, tops and extensions are placed upon the table 13st so as to be within easy reach of the attendant. A circular sheet metal plate 137 rests upon the radial chan nel bars 17 of the main table and closes the space between the inner ring 49 of the table and the shaft 35, thus hiding the said channel bars as well as the supporting mechanism and thereby adding to the artistic appearance of the table.

In Fig. 16, is shown a modification in the manner of Closing the dies upon the form. In this arrangement, the gears 64 and 66 and the rods 68 and 73 are dispensed with,

and the following mechanism is used: The

under side of the plate 51 is formed with a boss or hub 3 surrounding the hole through which the plunger operating eye bolt 99 passes, and upon the hub is rotatably mounted a disk 3 which is spacedfrom the plate 51by a-hub formed on the said disk as shown in Fig. 21. Adjacent the edge of the disk, or in opposite ears 3 formed 011 the edge of the disk, are holes in which are pivotally secured the inner ends of rods 8 and 3 one 'to the upper side of the disk and the other to the lower side thereof, as shown.

The outer ends of these rods are connected to eye bolts 3 which pass through depending abutment plates 3 secured to the cross bars 60 and 61 respectively. A coil spring 3 is placed upon each eyebolt between the abutment plate and a washer which is held against the adjacent end of the spring by a nut 3% WVhen the framesare open or apart, the disk 3 is in the position shown in Fig. 16.

Then the disk is turned in the direction of the arrow, the rods 5 and 5 are drawn upon, and the frames are drawn in and closed upon the form. When the dies engage the form, further pull on the rods is against the springs 3 and when the line of pull on the rods asses the center of the disk, the dies will be locked against the form. f

The disk 8 is operated by a lever 3 which is pivotally secured to the under side of the plate 51. The inner end of this lever is provided with a slot 3 and is connected to the disk by a bolt or pin 3 ,,which passes through the disk and through the slot 3 Other parts of the mechanism are the same as shown in the preceding figures.

In Fig. 17 is shown an adaptation of the rods and rotatable disk for operating four dies simultaneously. In this arrangei'nent, rods 3 are connected at their outer ends to eyebolts 3 which pass through abutment plates 3 on the pairs of die frames 3 and 3 which move in paths at right angles to each other. The inner ends of the rods 3 are pivotally connected in alternate order, to

theupper and under sides of the rim portion direct in and out movements, and the inward movements of these frames are cushioned by springs 3 which are interposed between the cross bars 3 of the frames and abutments 3 on the plate 51, the springs 3 surrounding rods 3 which are secured at one end to the cross bars and pass loosely through .theabutments 3" thus holdn the springs in place.

In Fig. 18- is shown an arran ement in which cablest take the place of t 1e rods 3 and are connected to the disk and to the eyebolts in the same manner as the rods. These cables pass over sheave wheels 4 which cause the cable to exert a direct pull on the die frames as will be understood by reference to the drawing. ,The cable bears upon the sheave wheel up to the point when its pivoted connection with the disk 3 is in direct line with the center-of the disk and with its eyebolt, and when the line of pull on the cable'passes the center of the disk, the cable moves away from the sheave wheel, and the frames are locked.

In making very small boxes, the die blocks 4 and 4 are arranged to accommo date two or more of such boxes, for each box forming and clamping mechanism as shown in Fig. 19, and in this connection the plungers are dispensed with, and the finished boxes are removed by hand. In this connection it is also preferable to use a manu ally operatedtable so that the attendant or attendants'may have sufficient time to complete each set;of boxes before turning the table in position for the next set.

In Fig. 19, is also shown a modification. in the sliding connection between the die blocks-and the plate 51;- In this arrange ment upon two oppositesides of the plate are bolted three brackets a, and in each set of brackets is secured a rod or track 4d. Each die block is provided on opposite sides with pairs of slides lin the formof brackets which are secured to the side edges of the die blocks and which are provided with lat eral n'o'ections havin alertures throu h which the rods or tracks 1d pass. These brackets or slides support the die blocks at a V slight'distance above the table so as to per mit their free hack and forth movement, as will be understood by reference to 20.

This sliding arrangement can be used in 7 connection with any means for operating the v *bers143'of the and a sprocket wheel 150 on its slidably mounted 'whichare mounted on, the shaft 147, 'as

tubes or; sleeves 52 are 140 and 141, in the depending lugs or' members 142 on their in-' shown. The die 90 is secured to the die frames.

In Figures 22, 23 and 24, I have shown a further modification in the mechanism for opening and closing the dies upon the form block. In this arrangement, the spacing dispensed with, and the metal plate 51 is supported upon opposite pairs of standards138 and standards, near their upper ends are formed with holes, and in the holes of each pairof' standards is secured a rod or track 139. Upon each rod is mounted a pair of slides form of fiat bars having ner ends and longer depending members 143 OIl'thGll outer ends, andthe members 142 and 143 are provided with holes through To the which the rod or track 139 pass. slides 140 are secured thedie 89, by screws 144, which extend down through slots in the side edges of the die and are screwed into the horizontal members of the'slide, as

141 in a similar manner by screws 145. By this arrangement, the dies are slidably mounted upon the track rods 139, to be moved back and forth with respect to the 'form block 88, and over the metal plate 51.

- The outward movement of the die 89 is limited'b'y engagement of the depending members 142 of the slide 140 with the adjacent standards 138, and the outward movement of thedie 90 is limited by of the depending members 142-of the slides 141 with the standards 138 A shaft 146, is rotatably mounted in bearing holes in the lower ends of the members 143 of the slides 140, and a similar shaft147, is mounted in bearing holes-'n the lower ends of the memslides 141'.- Upon the shaft 146 is rigidly mounted a pair of hubs 148, each having a depending arm 3 other end.

T o'the lower ends of the arms 14.9 are pivotally attached socketed links 151 in which are secured the'forward ends of a pair of rods 152, the opposite ends of which are in socketed members 153 clearly'sho'wn in'Figs. 22 and 24.

V at one end Coil springs 154 surround'the rods 152,

and are held under tension between the ends of the links 151, and'the socketed members 153. The sprocket wheels150 perform only a partial rotation and therefore it is only necessary to provide them with teeth throughout a half or three-fourths of a complete circle. Sprocket chains 155 are secured to the wheels 150, and pass over and aroundand under the said wheels, and

extend forward slightly above the table top, and their'opposit e ends are secured to ears -nected= by a channel bar other features .of

7 138 which are secured to the table sections 50. These slides f the track rods 139 until the depending lugs 142 engage the standards 148,- and further engagement with the die 90, are

149 on one end sprockets i to permit 156 which depend from the hub portions 157 of the socketed members 153. z

The shaft 146 is providedwith operating handleTT, and the members 143 are con- 158 to hold them in rigid relation. As the arrangement shown in Figures 22 -and-24, refers only to the die opening the machine have-been omitted in these views, but it willbe understood that these features can be used in connection with the mechanism shown inFigures 22, 23 and 24,v without any change in either their construction or arrangement.

' The operation of the last described mechanism is as follows: Assuming that the dies 89 and90' are closed upon the form 88, then the operating handle 77 is moved in the direction of the arrow, thereby turning the shaft 146, the arms 149 and the sprocket wheels 150; But as thelowerends of the 'arms 149 are pivotally connected to the links 151 which are under outward pressure from the springs 154, the said links form fulcrumsfor. the arms 149, whereby the slides 140- with the dies 89 are moved outward on outward. movement of the die 89 is prevented.

The standards 138 now act as fulcrums and as the arms 149 are swung'toward horizontal position, the links 151pushiagainst the springs 154, which in turirpush against the socketed members 153, and the slides 141,

tracks 139, and away from the form block 88, until the depending members 142 on the said slides 141 engage thestandards 138 and closing mechanism,

slid outward upon the and prevent further movement of the slides.

Furthermovement of'the arms 149 is now a 'ainstthetension of the springs 154, and

the rods 152 therefore, slide inward in the socketed members 153, until theline of push on -the' rods passesabovethe centers of the shafts 146 and 147 when the springs act-to lock the arms 149', and thus hold the dies in open position.- During these movements of the slides, the chains 155 unwind from the such movement, as will be understood.

' When the handle 77 isturned to close the dies, thechains 155 wind upon the sprocket wheels 150, and the slides 140are thereby drawn inward until they contact with the form block, after which the chains draw the slides 141 inward until the die also contacts with the for-m block, at which time the handle 77 passes a vertical line, the arms 149 are in vertical position and the springs 154 are undertension between the ends of the links 151 and the ends of the socket members'153, and thus ilock thedie in resilient contact with: the form 88, as will be understood byreference to Fig. 22.

Instead of the sprockets and chains, I may employ belts and pulleys, the belts being secured at one end to the pulleys and at their opposite ends to the socket member 153.
